    • An electromagnetic contactor has a contact device having a pair of fixed contacts and a movable contact; and an electromagnet unit including an exciting coil driving a movable plunger connected through a connecting shaft. The contact device is configured such that L-shaped portions have a contact portion formed in the pair of fixed contacts fixed maintaining a predetermined interval, and two ends of the movable contact are disposed to be capable of contacting to and separating from the contact portions of the L-shaped portion on a side opposite to that of the electromagnet unit. The electromagnet unit includes a magnetic yoke enclosing a plunger drive portion, a movable plunger having a leading end protruding through an aperture formed in the magnetic yoke and urged by a return spring, and a ring-form permanent magnet magnetized in a movable direction of the movable plunger and fixed to enclose a peripheral flange portion.

    • The present invention provides a contact mechanism that is capable of, without enlarging the entire configuration thereof, preventing the generation of an electromagnetic repulsion that opens a movable contact upon application of a current, and also provides an electromagnetic contactor that uses this contact mechanism. A contact mechanism (CM) has a fixed contact (2) and a movable contact (3) that are inserted in a current-carrying path. In the contact mechanism (CM), at least either the fixed contact (2) or the movable contact (3) is formed into an L-shape or a U-shape so as to generate a Lorentz force that acts against an electromagnetic repulsion in an opening direction, which is generated between the fixed contact (2) and the movable contact (3) upon application of a current.
    • 本发明提供一种接触机构,其能够在不扩大其整体结构的情况下防止在施加电流时产生打开可动接点的电磁斥力,并且还提供使用该接触机构的电磁接触器。 接触机构(CM)具有插入通电路径中的固定触点(2)和可动触点(3)。 在接触机构(CM)中,至少固定触点(2)或活动触点(3)中的至少一个形成为L形或U形,从而产生用于抵抗电磁斥力的洛伦兹力 在施加电流时在固定触点(2)和可动触点(3)之间产生的打开方向。
